As illustrated in FIG. 5A, the lamp 30 includes an LED (Light Emitting Diode) 31, a substrate 32 on which the LED 31 is mounted, and a housing 33 that accommodates the substrate 32.
The lamp 30 is configured along the width direction of the ceiling panel 20 orthogonal to the front-rear direction of the passage 13.
A plurality of LEDs 31 are arranged along the length direction of the lamp 30.
Note that other types of light sources may be used instead of the LEDs 31. Moreover, although white LED is employ | adopted in this embodiment, you may comprise so that the color of light may be changed regardless of the color of a light source.
The surface of the substrate 32 is coated with white paint in order to efficiently reflect the light emitted from the LEDs 31.

The housing 33 includes a back plate 34 that supports the substrate 32 and a lens cover 35 that is attached to the back plate 34 so as to cover the LEDs 31.
The lens cover 35 has an irradiation surface 351 that faces the back plate 34.
The lamp 30 makes the light emitted from the LEDs 31 uniform over the entire irradiation surface 351 and irradiates the irradiation surface 351 in the out-of-plane direction.

As shown in FIG. 3, a receptacle pin 38 as an electrical connector is provided at the left end portion of the back plate 34. A plug socket 39 connected to a wiring 39 </ b> A provided along the support member 14 is attached to the receptacle pin 38. The receptacle pin 38 and the plug socket 39 are located in the vicinity of the hinge 15 (FIG. 4).
A spiral groove (not shown) is formed on the outer periphery of the receptacle pin 38. The plug socket 39 is inserted into and removed from the receptacle pin 38 along the axial direction while rotating in the circumferential direction by being guided by the spiral groove.

Next, a structure for assembling the lamp 30 to the step portion 25 of the ceiling panel 20 will be described.
As shown in FIG. 5A, the lamp 30 is assembled to the ceiling panel 20 by a rear bracket 36 and a front bracket 37, both of which are substantially L-shaped resin molded products.
The rear bracket 36 is a plate-like first piece 361 that is bonded to the back surface of the rear end portion 23 of the ceiling panel 20 and a plate that rises from the back surface of the rear end portion 23 and is fixed to the back plate 34 of the lamp 30 with screws. And a second piece 362 having a shape. A pair of reinforcing walls 363 and 363 are formed inside the first piece 361 and the second piece 362. As shown in FIGS. 6A and 6B, the reinforcing walls 363 and 363 stand upright from the first piece 361 and the second piece 362 at intervals in the length direction of the lamp 30.

As shown in FIG. 5A, the front bracket 37 rises from a plate-shaped first piece 371 that is bonded to the back surface of the ceiling panel 20 at a position higher than the rear end portion 23, and the back surface of the ceiling panel 20. A plate-like second piece 372 fixed to the back plate 34 via the spacer 40. On the back plate 34, a protruding piece 34A (FIG. 3) for fixing the spacer 40 is formed.
The second piece 372 and the spacer 40, and the spacer 40 and the back plate 34 are fixed with screws. A pair of reinforcing walls 373 and 373 similar to the reinforcing walls 363 and 363 of the rear bracket 36 are also formed on the front bracket 37.

The spacer 40 can have an arbitrary shape such as a rectangular parallelepiped shape or a cylindrical shape. The form of the spacer 40 is selected from the viewpoints of dimensional accuracy, component cost, ease of assembly, and the like.
Since the spacer 40 shown to Fig.5 (a) is formed in a block shape by cutting, a tolerance can be restrained severely. When assembling the lamp 30 to the ceiling panel 20, it is possible to finely adjust the dimensions by adding shims or cutting. It is preferable that the spacer 40 be formed lightly with resin.
On the other hand, the spacer 41 shown in FIG. 5B is formed in a U shape from a metal plate. The spacer 41 is arranged so that the web 411 faces upward and the opening 412 side faces downward.
Since the spacer 41 can be elastically deformed so as to narrow the space between the flanges 413 and 413, the spacer 41 can be easily inserted between the back plate 34 and the front bracket 37. The spacer 41 can be formed at a low cost by sheet metal processing.

When the lamp 30 is assembled to the ceiling panel 20, the lamp 30 is inserted between the rear bracket 36 and the front bracket 37 that are bonded in advance to the ceiling panel 20, and the rear bracket 36 is fixed to the back plate 34 and the spacer 40. The front bracket 37 is also fixed to the back plate 34 via.
Then, the lamp 30 is integrated with the ceiling panel 20 in a state where the irradiation surface 351 is exposed to the outside from the opening 26 of the ceiling panel 20.

  The assembly tolerance can be absorbed by distortion on the upper end side of the back plate 34. As shown by a two-dot chain line in FIG. 5B, the upper end side of the back plate 34 can be distorted around the front bracket 37 to absorb the dimensional variation, so that the entire lamp 30 fixed by the rear bracket 36 is inclined. can avoid. Therefore, since the lamp 30 irradiates a predetermined direction, the appearance of the lamp 30 and the irradiation performance are not affected.

As shown in FIG. 3, the rear bracket 36 is disposed at the left end, the right end, and the center portion of the back plate 34. The front bracket 37 is disposed at two positions between the three rear brackets 36, respectively.
Here, the position of the rear end bracket 36 at the left end is close to the receptacle pin 38 and the plug socket 39. Therefore, the height of the reinforcing wall 363 is kept low in order to make it easy to attach and detach the receptacle pin 38 and the plug socket 39 (FIG. 5). Further, the reinforcing wall 363 gradually decreases from the corner formed by the first piece 361 and the second piece 362 toward the tip 361A of the first piece 361 and the tip 362A of the second piece 362. Further, all corners of the reinforcing wall 363 are chamfered.

As shown in FIG. 1, the lamp 30 provided in each of the plurality of ceiling panels 20 emits light from the rear side of the passage 13 toward the front side with an interval of one ceiling panel in the front-rear direction of the passage 13. Irradiate. The light emitted from each lamp 30 along the direction orthogonal to the front-rear direction of the passage 13 over almost the entire width of the ceiling panel 20 illuminates the cabin while repeatedly casting a pattern on the relief 21 of the ceiling panel 20.
The light radiated forward from the plurality of lamps 30 can improve the appearance of the cabin. In addition, since the passenger is welcomed into the cabin by the light emitted from each lamp 30, it is possible to produce the brightness in the cabin.
Here, since the lamp 30 emits light toward the front, the passenger sitting on the seat sees the indirect light after reflection and diffusion without directly viewing the light emitted from the lamp 30. For this reason, it can spend comfortably, without feeling dazzling.

When the lamp 30 is maintained and inspected, the right end portion of the ceiling panel 20 is pulled downward, and the ceiling panel 20 is rotated about the hinge 15 as a rotation center, as shown in FIG.
At this time, since the receptacle pin 38 and the plug socket 39 are located in the vicinity of the hinge 15 whose position does not change even when the ceiling panel 20 is rotated, the wiring 39A is pulled out with the rotation of the ceiling panel 20. There is nothing.
When the ceiling panel 20 is rotated, the ceiling panel 20 hangs on the ceiling structure, and accordingly, the entire lamp 30 is exposed on the back side of the ceiling panel 20. At this time, it is preferable that the ceiling panel 20 is held at a predetermined rotation angle that stands with respect to the support member 14 by a mechanism provided on the support member 14 or the like.
The ceiling panel 20 is rotated about an axis along the front-rear direction of the passage 13 and hangs in a posture along the traveling direction of the passage 13. Therefore, it is possible to proceed with maintenance and inspection while going up and down the passage 13 with the ceiling panel 20 raised. Work with the plurality of ceiling panels 20 raised at once can be performed without any trouble.

With the ceiling panel 20 raised, the entire lamp 30 and the lens cover 35 are replaced.
At this time, it is not necessary to reach for the ceiling in order to replace and inspect the lamp 30, and the maintenance staff can stand in the passage 13 and handle the lamp 30 in an easy posture.
In addition, since the ceiling panel 20 is hung from the ceiling, the ceiling panel 20 is not troubled with the storage, unlike the ceiling panel that is completely separated from the ceiling structure.
Therefore, according to the ceiling lighting device 10 of the present embodiment, maintainability can be improved.

When replacing the entire lamp 30, the plug socket 39 is removed from the receptacle pin 38 of the lamp 30. Therefore, when a maintenance worker standing on the right side of the ceiling panel 20 works with the right hand, the plug socket 39 is gripped so that the thumb is positioned in the area F1 and the index finger is positioned in the area F2 shown in FIG. The part 391 (FIG. 6B) is gripped. Then, the plug socket 39 is moved backward with respect to the receptacle pin 38 while rotating in the direction of the arrow Rr. Due to the rotation at this time, the index finger (F2 region) approaches the rear bracket 36, but the plug socket 39 moves away from the rear bracket 36 by the axial stroke St shown in FIG. Does not interfere.
Further, when the plug socket 39 is attached to the receptacle pin 38, the index finger (F2 region) moves away from the rear bracket 36 because the plug socket 39 is rotated in the direction of the arrow Rc. Does not interfere.
Moreover, since the height of the reinforcing wall 363 of the rear bracket 36 is suppressed as described above, the fingers do not interfere with the rear bracket 36, and maintenance can be performed comfortably.

In addition to the above, as long as the gist of the present invention is not deviated, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
In the above-described embodiment, the hinge 15 serving as the rotation center of the ceiling panel 20 is located on the left side of the ceiling panel 20 with respect to the traveling direction of the aircraft. Of course, the rotation axis of the ceiling panel 20 may be set on the right side. it can. Moreover, the rotational axis of the ceiling panel 20 can also be set to the front side or the rear side.
Further, the ceiling panel 20 can be configured to be rotated around a rotation axis set on both the left and right sides, for example.
